"TypeError: Cannot read property 'call' of undefined" Roborock V1 Vacuum

[WhiteLionATX]

I know there is no official support for Roborock Vacuum. But it worked fine for a long time. 6 Month ago my Roborock switched off (battery) . Now I renewed the battery and hoped that it will continue working with this plugin... but It doesn´t. I removed the plugin from node red and reinstalled it. After a fresh installation it worked for 2 commands and stopped now again with error: "TypeError: Cannot read property 'call' of undefined". - I am using the example node for testing.
Any idea on that ?

EDIT: Console out:

how many vacuums do you use? try to install 2.0.7 version

Thanx for your fast answer.
I only own one cleaner and there is only this one entry for it configured in the properties.
I installed V2.0.7 and it doesn´t seem to help. Here is the console output on V2.0.7:

Controlling the cleaner by app works while the plugin shows errors and doesn´t work.

EDIT: I am not sure why but now it seems to work with V2.0.7. Maybe it has to do with connection issues. I will test and report back later.

I also experienced this error and updated to v2.2.2. I can confirm, that this issue is fixed in that Version.

I also get this problem with 2.2.4.

I have two robots (S50 and S6MaxV) Both where responding to commands when I tried it first. Later I wanted to finish the flow and added Alexa nodes and started tinkering. From that moment on I do only get this respond, whatever I am trying.

Rebooting the raspi helped...

I can confirm that it stopped working when going to 2.2.4 I downgraded to 2.2.2 and everything works fin again. Try:
npm install node-red-contrib-miio-roborock@2.2.2

Got the same error with 2.3.4, nodered running in docker, restart cleared the issue.
